SPINDLE CUTTER Filed March 3l, 1937 BY mzwLQf@ ATTORNEY Patented June 7, 1938 UNITED STATES 2,119,929 SPINDLE CUTTER Albert C. Schmitt, St. Nazianz, Wis.

Application March 31,

1 Claim.

This invention relates to cutters especially adapted for dressing down brake flange bearings of axle spindles for the purpose of bushing said bearings when worn to eliminate looseness and f noises incident thereto and has for the primary object the provision oi a portable and eicient device of this character which will be simple to operate and permit dressing down of bearings to be accurately accomplished andfwhich may be manufactured and sold at a low cost.

With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is aside elevation partly in section with my inventio-n.

Referring in detail to the drawing, the numeral I indicates a tubular shaped body in which is slidably supported a sleeve 2 provided with a bore 3 to receive an axle spindle 4. One end ofthe sleeve has a reduced opening of a size to receive the screw threaded reduced end 5 of the axle spindle. The axle spindle 4 is provided with a brake flange bearing 6 for supporting on the axle spindle a brake flange (not shown). After axle spindles of this character have been in use for a period of time the bearing 6 wears pro-f viding play between the bearing 6 and the brake drum flange. This play creates undesirable noise. The present practice when this wear occurs is to replace either the axle spindle or the brake drum flange, either of which is expensive. With the use of the present invention this excessive expense can vbe eliminated by dressing down the bearing 6 to permit-mounting thereon a bushing (not shown) for the `lpurpose of taking brake drum ange moving relative to thev bearing 6. The present invention, a portion of which has hereto-fore been described'v provides a very rotatably support a feed nut 9. -The feed nut 9 is grooved to receive the walls of the slot 8 illustrating a cutter constructed in accordance n up play and eliminate the noise caused by thev economical tool for dressing down the bearing 6. Secured in one end of the body I is anend plate A 1 having a key hole shaped slot 8 to receive and 1.937, Serial No. 134,181

and provides means for permitting the nut to rotate freely and be held against endwise movement with respect to the body I. VAt any time the feed nut can be removed from the plate 1 by moving said nut into the enlarged portionof 5 the key hole slot. A feed stem IIJ is threaded through the feed nut and one end is enlarged to form a head I I having a screw threaded socket I2 therein. The head is adapted to be threaded onto the reduced screw threaded end 5 of the 1 axle spindle and against the end of the sleeve 2. By rotating the feed nut 9 the sleeve 2 may be ,n advanced endwise of the body I for the purpose of advancing the bearing relative toV a cutting tool I3. f 15 Formed on the body I are spaced guide flanges Iflbetween which is received and pivoted thereto a tool holder I5. One end of the tool holder projects beyond one end of the body I and has the tool I3 adjustably secured thereto. The other end of the tool holder has threaded therein a 20 set bolt Iii engageable with the body for the purpose of regulating the depth of cut by the tool I3.

Secured to the body I intermediate its ends is a handle I1.

In operation, the tool is applied to an axle spindle, as shown in Figure 1, and the set screw I6 is adjusted to bring the cutting tool I3 in engagement with the bearing ofy the spindle axle and by rotating the body I about the axle spindle and turning the nut 9 the cutting tool I3 win be 30 caused to remove a portion of the face of the bearing .about the entire Vcircumference of the bearing as well as the length of the bearing.

What is claimed is:

Acutter comprising a tubularshaped body, a sleeve having said body slidable thereon and provided with a bore to receive an axle spindle with one end af the latter `projecting beyond one end of said sleeve, a plate closingone end of the body and having a key hole shaped slot, a feed nut having an annulargroove journaled 0n the plate by the walls of theslot fitting in the groove of said feed nut, a feedstem received by the feed nut and extending into the body, a head formed on the feed stem and bearing against the sleeve and threaded on the axle spindle, a handle se'- cured on said body,` spaced flanges V formed on said body, a tool holder pivoted on said flanges, a cutting tool carried by said holder, and an 5 adjusting screw carried by said holder to engage with the body for adjusting the cutting tool relative to a bearing on the` axle spindle.
